Question

which best states the theory of plate tectonics?

earths layers consist of the crust, the mantle, the outer core, and the inner core.

earths most active volcanoes and earthquakes occur in the ring of fire.

earths surface is made of different sections of rock that move apart and collide.

earths continents were once joined together as one landmass.

Explanation:

• The first option describes Earth's internal layers, not plate tectonics.
• The second option is about the location of active geological features, not the theory of plate tectonics.
• The third option correctly states that Earth's surface is composed of tectonic plates (sections of rock) that move, collide, or separate, which is the core of plate tectonics theory.
• The fourth option is part of the continental drift theory (a precursor to plate tectonics), but it doesn't fully state the plate tectonics theory.

Answer:

C. Earth's surface is made of different sections of rock that move apart and collide.
